Hi all,
I have a ISDN issue here, ISDN keep dropping after 20 second exactly, below is the debug captured during the problem:

Sep 30 00:41:19.870 GMT: ISDN BR0/3/0 Q931: DISCONNECT pd = 8 callref = 0x0D
Cause i = 0x8090 - Normal call clearing
Suspect it could be local telco issue, however, telco already feedback that their side is clean, please kindly advise.
